MACHINE FOR MAKING SHOE-TREES.

Application filed `Tune 20, 1923. Serial No. 646,697.

To all whom t may concern:

Be it known that I, LoUIs F. VoIsARD, a citizen of the United States, resident of Galion, county of Crawford, and State of Ohio, have invented new and useful Improvements in Machines for Making Shoe- Trees, of which the following is a specifica tion, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. My invention relates to machines for making shoe-trees and particularly to apparatus of this character designed automatically to assemble the usual toe and heel forms of these trees with the intermediate iexible connector or'bodyportion of the shoe-tree. Also, the invention relates to machines of mechanism is provided for rigidly fastening the flexible connector to the forms, irrespective of the particular means by which the forms and connector are initially assembled. Improvements are also shown and claimed for new clamping mechanism designed temporarily rigidly to hold the flexible connector while the wooden forms are vforced thereon.

The annexed drawings and the following description set forth in detail certain means ,embodying my invention, such means constitilting, however, but one of the variousforms in which the principle of the invention may be applied.

In said annexed drawings:

Figure 1 represents a fragmentary plan view, 'showing particularly the top of a working table and the arrangement of mechanism thereon.

Figure l'nl represents a fragmentary vertical section,`upon an enlarged scale, taken in the plane 'indicated by the line Ia- F l.

45 Figure 2 is a front elevation of the machine.

Figures-3 and 4, represent, respectively, a plan view and a side elevation of the driving mechanism.

Figure 5 is a fragmentary vertical section, upon an enlarged scale, showing the starting position of certain cams designed to clamp the steelconnector rigidly in place previousthis character in which specific nailingv ly to the .movement of the wooden forms to- Ward and onto the ends of said connector.

Figure 6 is a fragmentary side elevation, upon an enlarged scale, showing the starting position ofcertain cams whose function is to force the wooden forms onto the ends of the flexibleconnector; and

Figure 7 is a fragmentary vertical section, upon an enlarged scale, of certain cams adapted to effect the nailing of the forms to the intermediate connector.

Referring to the annexed drawings in which the same parts are indicated by the same respective ordinals in the several views, I indicate a supporting frame by the ordinal l having a work table 2. A motor 3 is suitably supported in the frame 1 and is adapted to rotate a pulley 4 secured to a shaft 5 which through intermediate gearing 6 is adapted continuously to rotate a main driving shaft 7 which, through the medium of a clutch 8 controlled by a foot-treadle 9 and atreadle rod 10, can be coupled, as desired,

to al cam shaft l1. v

The design of the machine is to assemble certain' shoe-tree forms, illustrated by the toe-form 24 and the heel-form 25, and a body portion or flexible intermediate steel band or connector 23, the same being automatically effected through the proper functioning of certain cams secured to the cam shaft ll, the operation including the initial clamping of the steel band 2 3 so 'that the assembling can be accomplished by forcing' the forms 24 and 25 onto the ends of the band 23. V'Ihe invention also includes further the rigid fastening of the forms 24 and 25 to the band`23 by means of automatically forcing nails 47 through holes 48 in the band 23, after the latter has been assembled in the forms 24 and 25, irrespective of the particular method ormeans by which the initial assembling of the forms 24 and 25 and theband 23 has beeneflected.

First, the wooden pieces or forms 24 and 25 are inserted by hand in suitable containers 3 6 and the band 23 is inserted by hand in a wedge-shaped groove 52 formedT in the top of the. two-cooperating separable halve-s of an auxiliary table 27 mounted upon the main table 2. The exact position of the band 23 is determined b-y a spring-mounted guide pin 26 mounted inthe table 2 kand whose t 1 protruding end is substantially of the same length as the proper length of one extending end`23 ot the steel band 23 to insure the correct position of the latter relative to the operating elements of the machine. The cam shaft 11 then being thrown into action through the medium of the clutch 8, a pair ot cams 12 act upon rollers 13 mounted between the arms 15 of yo-les 14 having heads 1G to which are secured pins 17 adapted to reciprocate within horizontal recesses 18 1n the table 2, all to force clamping blocks 21 secured to said pins 17 against the ends of the steel band 23 rigidly to hold the same, collars 19 being secured to the pins 17 at a spaced distance from the table 2 in the initial position ot' the cams 12, another pair ot collars 20 loosely encircling the pins 17 and guiding the same adjacent the clamping blocks 21, so that coil-springs 22 are compressed between the collars 19 and 20, as the pins 17 and clamping blocks 21 move inwardly to hold the band 23. Next, a second pair ot' cams 29 act upon rollers 30 secured to rock-levers 31 suitably pivotally-mounted, to the: other end of which levers 31 are secured rollers 82 disposedadjacent to heads 38 upon pins 34 secured in and projecting ilrom blocks disposed adjacenet to the receiving members 36 for the forms 24 and 25. The blocks and the members 36 are slidaibly mounted in -the table 2, so that it Ais evident that the eil'ect of the rotation of the cams 29 will be to force the forms 24 and 25 against and onto the ends of the steel band 2B and cause said ends to be inserted in said forms. Coil-springs 49 are contained within suitable recesses 54 within the table 2 and are put under tension during this inward movement off the blocks 35, through the medium of plates 53 clamped to the blocks and over the openings of the recesses 54, and between which plates 53 and the inne-r walls of the recesses 54 said springs 49 are contained.

rPhe foregoing means which have been described in detail effect the assembling of the toe and heel forms and the intermediate steel band, the same being lrepeated automatically as fast as the complete articles are removed and the p-arts for a succeeding tree are inserted in the machine, the springs 22 and 49 retrieving the 'mechanism so that all ot' the elements are restored to their ini-` tial starting position, as will bev readily understood. Now, irrespective of the mechanisms for thus assembling the tree elements, l shall describe and have shown in the accompanying dra-wings, elements for nailing the 'forms to the intermediate connector so that there is no possibility of the sam@ pulling apart. 'I have shown this nailing mechanism in connection with the other improved mechanism for assembling the trees which has already been described. This nailing function is eiected by the action of a third pair of cams 37 which act upon rollers 38 secured to rock-levers 39, the outer ends of said levers, 39 being secured to the lower ends ot vertically-disposed pins 40 whose upper ends are secured to the ends, respectively, of a bar 41 secured to and intersecting a casing 42 which in turn is secured to and intersects a pair ot blocks 43 disposed somewhat inwardly otl the ends of theI bar 41 and carrying depending bars 44 adapted to reciprocate within housings 45 mounted upon blocks 55 secured to the auxiliary table 27 and having feed chutes 46 for nails 47, these chutes being adapted to discharge the nails 47 in vertical alignment with the holes 48 formed in the ends of the steel connector 23. The lower ends ot the depending bars 44 lie adjacent the top of the nails 47 as the same are discharged from the chutes 46, so that the downward movement of the bars 44 caused by the movement of the trame 42 when the. levers 39 are rocked, will cause said bars 44 to force the nails 47 through the forms 24 and 25 to intersect the holes 48. The nails 47 may be furnished to the chutes 46 either manually or by any suitable automatic 'feed device, the particular means not forming any part of this invention. The inner ends of the levers 39 rock upon a bar 51 suitably mounted in the frame and coiled upon this bar is a spring 50 whose respective ends lie beneath the inner ends ot the levers 39, as plainly shown in Figure l. It is evident that the downward movement of the inner ends ot the levers 39 will put the spring 50 under tension and that the continued krotation of the cams 37 will release the levers 39 and will permit the spring 50 to rock the levers 39 to their initial starting position.
